    摘要： A synthesis gas plant for producing a synthesis gas, where the synthesis gas plant includes a reforming section arranged to receive said feed gas and provide a combined synthesis gas, wherein said reforming section includes an electrically heated reforming reactor, a fired reforming reactor and an optional third reforming reactor. The reforming section is arranged to output a combined synthesis gas. An optional post processing unit downstream the reforming section is arranged to receive said combined synthesis gas stream and provide a post processed synthesis gas stream. A gas separation unit arranged to separate the combined synthesis gas stream or the post processed synthesis gas stream into a condensate, a product synthesis gas and an off-gas. At least a part of the off-gas is recycled from said gas separation unit to said one or more burners. Also, a process for producing synthesis gas from a feed gas comprising hydrocarbons.
